Enables extensions to implement customized behavior when the user types into the browser's address bar.
When the user focuses the browser's address bar and starts typing, the browser displays a drop-down list containing suggested pages based on what they typed. This gives the user a quick way to access, for example, pages from their history or bookmarks.
The omnibox API provides the extension a way to customize the suggestions displayed in the drop-down, when the user enters a keyword defined by the extension. It works as follows:
- First, the extension must include an "omnibox" key in its manifest.json file, which defines a keyword.
- When the user focuses the address bar and types the keyword followed by a space, the extension gets an
- Optionally, the extension can call
omnibox.setDefaultSuggestion()to define the first suggestion displayed in the address bar drop-down.
- As the user continues to type characters, the extension gets
omnibox.onInputChangedevents. The event listener is passed the value the user has typed and can populate the address bar drop-down with suggestions. If the extension sets a default suggestion using
omnibox.setDefaultSuggestion(), this suggestion is displayed first in the drop-down.
- If the user accepts a suggestion, the extension gets an
omnibox.onInputEnteredevent. The event listener is passed the accepted suggestion.
- If the user deletes a suggestion, the extension gets an
- If the user dismisses the drop-down, the extension gets an
